HAND-SPRAYER.

SPECIFICATION forming part of Letters Patent N 0. 732,092, dated June 30, 1903. Application filed January 2, 1903. Serial No. 137,530. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. LISK, of Clifton Springs, in the county of Ontario and State of New York, have invented a new and usefulImprovement in Hand-Sprayers, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

My invention is an improved hand-sprayer for use in spraying shrubs and low plants and other vegetation, as for garden use, the same being hereinafter fully described, and more particularly pointed out in the claims. Sprayers of this class heretofore produced have been costlyin structure and make; and one of the main objects in providing this improved device has been to furnish a sprayer that can be produced at low cost and sold to the purchaser at a price readily within reach. In pursuing this object one aim has been to construct the parts so that when put together the outflow-tube for the spraying liquid will of itself always assume a position of true alinement with the air-jet or outflow-opening of the air-pump.

A further object of the invention is to so construct the pump that the outer end of the suction or outflow tube will be protected against injury.

A further object of the invention is to provide means by which the outflow-tube may be readily probed 0r cleared of obstructions, although its discharge end is partially covered for its protection.

Other objects and advantages of the invention will be brought out and made to appear in the following specification, reference be-.

ing had to the accompanying drawings, forming a part thereof.

Figure 1 is a side elevation of my improved hand-sprayer with parts broken away. Fig. 2 is an end view of the device seen as indicated by arrow in Fig. 1. Fig. 3 is a side elevation of parts at the forward or operative end of the pump-barrel, parts being broken away and diametrically sectioned on the dotted line 3 3 in Fig. 2. Fig. 4 is aview of a part at the forward end of the pump seen from above, parts being broken away and diametrically sectioned on the dotted line 4 4 in Fig. 2. Fig. 5 is a plan of the head of the air-pump detached, further showing the form thereof. Fig. 6 is a longitudinal section ofa part of the pump barrel and head, taken on the dotted line (i 6 in Fig. 5. Fig. l is drawn to a scale one-half the size of the remaining figures.

Referring to the parts shown, A is an airpump designed to be operated by hand, it being of common construction except as to the delivery plate or head b.

B is a reservoirof common kind secured to the pump A for holding the spraying liquid. This reservoir is usually made cylindrical in form and placed beneath the forward end of the pump A, so as to project a short distance forward of the end of the pump, as shown in Figs. 1 and 3. The head b of the pump is pierced with a central opening afor the outflowing air, the upper end of the outflowtube d for the liquid being placed with reference to the opening a, as shown in Figs. 2 and 3, so the liquid will be broken into spray as it emerges from the tube. The head I) is of novel form, it being shaped or struck into form from a circular disk of sheet metal and punched out at the center all at a single blow or operation. It is formed with a prominent annular concentric bead or ring 0, there being preferably an annular flat part or field 6 without the bead and a circular tlat field or partf within the bead, atthe center of which part f the outflow or air-jet opening a is formed. The head 0 is divided diametrically by transverse channels or valleys g 9, Fig. 5, the bottoms of which channels being about even with the respective surfaces ef. The bottoms of the channelsg g are preferably made circular in cross-section, so the tube d when in place will rest snugly therein, as clearly shown in Figs. 4 and 6; but if found convenient in manufacturing the Sprayers the sides of'the channels may correspond with inclined planes giving a V shape to the form of the cross-sections of the channels. The channels being accurately formed across the head 0 and the tube (I placed in one and secured, as shown, said tube will be in accurate alinement with the circular opening a, the axes of the tube and of the opening accurately intersecting as a consequence of the formation of the parts and without care being taken to aline the tube. This is of great importance in the matter of manufacturing Sprayers, for the successful and perfect spraying of the liquid depends much upon the exactness of the relative positions of the conducting-tube for the liquid and the opening for the cross-jet of air.

The annular head 0 of the pump-head b is purposely made prominent or high and the cross-channels g 9 deep, so the delivery end of the conducting-tube 61 will be beneath or within the plane of the ridge of the head, as clearly shown in Figs. 3 and 6, and thus be protected against injury from coming in contact with other bodies. Both channels g'g are alike, on account of which no care need be taken when assembling the parts as to which one receives the liquid-tube. The channels being in a line across the center of the head, the empty one is in position opposite the end of the tube to make room for the introduction into the tube of aslender rod or wire (shown by dotted lines at h, Fig. 3) for clearing the tube should it at any time get fouled or clogged.

I usually prefer to incline the tube d, as.

shown in Fig. 3, though this is not essential to my invention. If the tube be thus inclined, when constructing the sprayer the headb of the pump will be formed to have the annular surface e lower or in a plane slightly back of the plane of the central part f, as shown. The tube when in place in a notch or channel 9 will be tangent to both surfaces cf, and resting against both gives it stability and firmness of position.

The head I) being formed and completed at a single stroke of the dies and secured by simple means to the end of the barrel A renders the construction of the sprayer simple and comparatively inexpensive, the costly conicalend piece heretofore commonly used being dispensed with.

I usually construct this sprayer with a tangent-foot D, Figs. 1 and 2, so that when laid down the sprayer will normally maintain a position in which the outer end of the tube d will be uppermost and so prevent the escape of the liquid from the reservoir.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A hand-sprayer com prising an air-pump, a reservoir and an outlet-tube for the liquid, the pump having a circular concentric bead, and the tube seated in a depression in said bead, substantially asdescribed.

2. A hand-sprayer comprising an air-pump and a reservoir, and an outflow-tube for the liquid, the pump being formed with a circular bead, and a perforated field within the head, the head having cross-channels, substantially as and for the purpose specified.

3. A hand-sprayer having an air-pump and reservoir, and a tube leading from within the reservoir, the pump havinga circular bead, and a perforation within the head, the bead being formed to receive the tube and hold it in accuratealinement with said perforation, substantially as shown and set forth.

at. A hand-sprayer comprising an air-pump and a reservoir, and tube coacting with both, the head of the pump being formed with a circular bead and perforation within, the end of the tube being within the outer plane of the bead and seated in a depression therein, substantially as and for the purpose specified.

5. A hand-sprayer comprising an air-pump and reservoir attached, and an outflow-tube for the liquid, the pump having a circular concentric bead, and a cross channel or notch in the head to receive the tube, substantially as shown and described.

6. A hand-sprayer having an air-pump and attached reservoir, the head of the pump having a circular bead and perforation within, a radial notch in the head, and an outflow-tube for the liquid in said notch, and an opening through the bead opposite the outflowtube, substantially as and for the purpose set forth. In witness whereof I have hereunto set my hand, this 29th day of December, 1902, in the presence of two subscribing witnesses.
